MILL FOR GRINDING CORN AND COBS.

Speccationof Letters Patent No. 3,524, dated April 4, 1844.

T 0 all 'whom z'tmay concern:

Be it known that I, SAMUEL L. HERR, of Mexico, in the county of Juniataand State of Pennsylvania, `have invented a new and useful Improvementin Mills for Crushing and Grinding Corn; and I do hereby1 declare thefollowing is a full, clear, and eX- act description thereof, referencebeing had to the accompanying drawings, which form a part of thisspecification, in which- Figure l is the isometrical representation;Fig. 2, detached parts.

The nature of my invention consists in forming a corn Aand cob Crusherand grinder by means of two vertical disks armed with teeth at thecenterand ribbed or channeled at their periphery the stationary'one having ahopper therein and the blade of a `shear and revolving disk carryingknives which cut against said static-nary blade. j

The construction is as follows: On a suitable frame (a) is aiiiXed adisk (b) in a vertical position having a projection `(c) fromvits centeron the outside and on one side of said projection a hopper (d) throughwhich the corn is fed into the machine. The projection (c) is forithepurpose of admitting a recess to be formed into the grinding face of thedisk (as shown A, Fig. 2). For about one quarter the diameter around thecenter the disk is plain and projects a little,

`outside of which is a ring of about the same width recessed into theface and studded around with coarse projecting teeth; in this ring alsois situated the aperture (cl) from the hopper along the lower edge `ofwhich is placed the stationary knife (e) extending across the ringhorizontally; beyond this ring are projecting ridges laid out similar tocast iron grinding mills of common construction gradually dishing outtcward the periphery about half its width after which it is flat asshown in section Fig. 3i.

Y The runner B, is cast with a shaft on which is a pulley (f) by whichit is driven, its outer end rests on the frame and it projects farenough through the grinding face of the runner to have a bearing in therecess of the stationary disk at the center as above named. Its grindingface is similar to the stationary one and is represented at B, Fig. 2,the differences between them being in the omission of the aperture foradmission of grain and the center ring does not project. This disk isarmed with two knives (i) that cut against the stationary knife (e) inthe disk attached to the frame. The boxes in which the shaft of therunner turns being i which I desire to secure by Letters is- Thecombination of the teeth and ridges with the knives in the mannerdescribed the whole being constructed and arranged for the purpose setforth.`
